Examples of org.apache.pdfbox.util.Matrix.concatenate()

            PDRectangle transformedBox = bbox.transform(matrix);


            // compute a matrix which scales and translates the transformed appearance box to align
            // with the edges of the annotation's rectangle
            Matrix a = Matrix.getTranslatingInstance(rect.getLowerLeftX(), rect.getLowerLeftY());
            a.concatenate(Matrix.getScaleInstance(rect.getWidth() / transformedBox.getWidth(),
                    rect.getHeight() / transformedBox.getHeight()));
            a.concatenate(Matrix.getTranslatingInstance(-transformedBox.getLowerLeftX(),
                    -transformedBox.getLowerLeftY()));


            // Matrix shall be concatenated with A to form a matrix AA that maps from the appearance��s

            // compute a matrix which scales and translates the transformed appearance box to align
            // with the edges of the annotation's rectangle
            Matrix a = Matrix.getTranslatingInstance(rect.getLowerLeftX(), rect.getLowerLeftY());
            a.concatenate(Matrix.getScaleInstance(rect.getWidth() / transformedBox.getWidth(),
                    rect.getHeight() / transformedBox.getHeight()));
            a.concatenate(Matrix.getTranslatingInstance(-transformedBox.getLowerLeftX(),
                    -transformedBox.getLowerLeftY()));


            // Matrix shall be concatenated with A to form a matrix AA that maps from the appearance��s
            // coordinate system to the annotation’s rectangle in default user space
            Matrix aa = Matrix.concatenate(matrix, a);
